Nice girl looking for a temporary rental

Hello! My name is Lisa and I'm a 20 years old girl looking for a rental up to end of June/beginning of July as I decided to move to Berlin for a while to see how do I like the city. I am a calm and friendly person who parties outside the house and treats home as a place of relax and work; that means I like to keep the space around me clean and tidy. My budget for a 1 room apartment is not too big but I also do not need much to feel at home and comfortable. I do smoke but I do not feel the need to smoke inside so it is not a problem if it's not allowed.
